Single bit error correction on NAND.

I have noticed that NAND support on MTD can detect/correct single bit errors
in 256 bytes, using software ECC. However, the correct data is not written
back to flash. In other words, the bit stays "flipped" in flash. Isn't that
dangerous? I mean, if another bitflip occurs in the same 256 bytes, we won't
be able to correct by software ECC...
Am I missing something here? Thanks in advance.
